Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a starting device for starting a grain dryer. The process is divided into three steps: stake-out work, drying work, and discharge work to take out υ1 grains after drying.

Drying work is carried out automatically, but since the amount of grain transferred during loading and unloading is large, grains are often scattered outside of the machine using dust extractors, and unnecessary exhaust machines and dust extractors are used. Rotating the machine consumes a lot of electricity, and the rotation also makes a lot of noise.

The present invention is intended to eliminate such drawbacks, and for this purpose, the following technical measures are taken. That is, the grains flowing down from the upper tempering chamber (1) to the lower drying chamber (2) are heated by a burner (3) and ventilated by an exhaust fan (4) while being dried. (5) to the dryer (6) which circulates to the conditioning chamber (1).
5) and a tensioning switch (7) that drives the burner (3).
), and a drying switch (8) that drives the exhaust fan (4), etc.
), each of which is independently operable, constitutes a starting device for a grain dryer.

With this configuration, the present invention has the following technical effects. That is, when the tensioning switch (7) is turned on, the elevator (5) is driven to supply grains to the upper conditioning chamber (1), and after the grains are tensioned, the drying switch (8) is activated.
The burner (3) is driven to cause combustion, and the exhaust fan (4) is driven to blow hot air into the drying chamber (2), heating the grains flowing through this drying chamber (2). After drying the grains, burner (3) and exhaust fan (
4), etc., and continue driving the elevator (5) to discharge the grains outside the machine.In this way, during the loading and unloading work, the exhaust fan (4) and the dust Since the UFX machine (9) etc. do not operate, there is no wasted power consumption, and the UFX machine (
4) and the dust extractor (9) are not operating, so there is little noise from rotating noises, and quiet tensioning and discharging work can be carried out.
Focusing on the two operations, the tensioning switch (7) and the drying switch (8) can be simplified by turning on and operating both at the initial stage.

To explain the example below, the dryer (6) has a lower helix (10) for transporting grains at the bottom, a ventilation chamber formed of perforated iron plate and communicating with the eight (3), and an exhaust fan. (4), a drying chamber (2) formed between the dust removal chamber and the drying chamber (2), and a feeding roll (11) at the lower end of the drying chamber (2), and a ceiling of the tempering chamber (1) at the top. There is an upper helix (12) for grain transfer in the section, and a spreading device (at the end of this upper helix (12)).
33) etc. is installed, and this dryer (1) is installed.
At the front of the burner case (1), there is a built-in burner (3) and an electromagnetic pump that supplies fuel to the burner (3).
3), and the exhaust fan (4) and this bell) are attached to the rear.
(14) An interlocking motor (15) is fixed, and an elevator (5) is attached to the front side of this dryer (6), and a motor (te) is attached to the upper side of the elevator (5). The belt (17) is then passed over the upper helix (12). The elevator (5) has a structure in which a belt (21) having a bag (20) is hung between the pulleys of an upper shaft (18) and a lower shaft (18), and a belt (22) is passed between the pulleys of an upper shaft (18) and a lower shaft (18). Upper spiral (I
2) A hook is provided between the shaft end and the upper shaft (18). The lower shaft (19) and the shaft end of the lower helix (10) are connected to each other by a bell (23), and the lower helix (10) is connected to a clutch pulley that is moved into and out of contact with the rotating operation of the clutch lever (24). (25) is provided. At the rear of the lower part of the dryer (6), a belt (
26) to drive the deceleration device (27),
A chino (28) is passed between the speed reducer (27) and a tin rocket provided thereto to drive the delivery roll (11). A dust remover (9) and a dust remover drive motor (29) were integrally constructed and fixed to the second part of the upper spiral (12). At the front of the dryer (6), there is an operation box (30) consisting of a tensioning switch (7), a drying switch (8), a stop switch, a display section, etc., and a moisture measuring device (
31). (34) is a timer.

To start the dryer (6), turn on the tensioning switch (7) in the operation box (3o), and the motor (16) will drive, interlocking the elevator (5) and the hill helix (12) to perform the tensioning work. I do. The drying operation is performed by turning on the drying switch (8) of the operation box (30), and at this time, the lower helix (io) and the feeding roll (11) are moved through the belts (23), (28), chino (28), etc. The grains are fed out by the rolls (
11) to the lower part, transported by the lower helix (10), fed into the elevator (5), transported to the upper part by the elevator (5), and then transported by the upper helix (12) to the diffusion device (33).
), and is evenly diffused and reduced in the conditioning chamber (1) in the diffusion device (33), where it is circulated and dried. burner (3),
Dust extractor motor (15) and dust extractor motor (28)
is driven, and the hot air generated from the burner (3) is sucked into the rear exhaust by the machine (4), which crosses the drying chamber (2) made of perforated iron plate and causes the hot air to flow through the drying chamber (2). The grains flowing down are exposed to hot air and dried. The moisture measuring device (31) measures the moisture, displays the moisture transfer status one after another, and when the specified moisture is reached, automatically controls the operation box (3o) to stop the burner (3) and start the timer (34). After that, the M ejector (4) and the dust ejector (9) are stopped. During the discharge operation, since the tensioning switch (7) remains in place, the dried grains are discharged to the outside of the machine by switching to the discharge chute (32) at the starting end of the upper spiral (12).
